[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. Example

[0023] like Figures 1-5 As shown, this utility model provides a technical solution: a ball mill screening device, including a ball mill assembly 1 and a screening assembly 2. A dust collection assembly 3 is provided on the side of the screening assembly 2. The ball mill assembly 1 includes a ball mill 101, with a discharge port 103 installed at one end. The screening assembly 2 includes a screening box 201, with multiple collection boxes 202 installed inside. Each collection box 202 has a screen 203 installed at its bottom. The dust collection assembly 3 includes a suction... The dust hood 301 has a connecting pipe 302 connected to its side. A dust collection box 303 is installed at one end of the connecting pipe 302. A suction fan 304 is installed on the side of the dust collection box 303. A filter element 306 is installed inside the dust collection box 303 and is located on the side of the suction fan 304. A protective frame 305 is installed on the outside of the suction fan 304. A sliding groove 307 is symmetrically installed on the side of the dust collection box 303. A sealing plate 308 is installed inside the sliding groove 307.

[0024] In this embodiment, during the sieving process, the suction fan 304 generates suction, which allows the dust hood 301 to absorb the dust generated during sieving. The dust is then collected inside the dust collection box 303 via the connecting pipe 302, effectively cleaning the dust generated during sieving, reducing the dust concentration in the workplace, protecting the respiratory health of operators, and effectively controlling dust emissions, reducing pollution to the surrounding environment, which is beneficial to environmental protection. The filter element 306 prevents dust from entering the suction fan 304, ensuring the normal operation of the suction fan 304. The protective frame 305 further protects the suction fan 304. The movable sealing plate 308 slides inside the slide groove 307, facilitating the cleaning of the dust collected inside the dust collection box 303. Example

[0025] like Figures 1-5 As shown, multiple bouncing balls 204 are distributed inside the screen 203. A vibration motor 205 is installed on the side of the screening box 201. Buffer dampers 206 are installed at the four corners of the bottom of the screening box 201. A feed inlet 102 is installed at one end of the ball mill 101. A gear ring 105 is installed on the outside of the ball mill 101. A gear disk is meshed on the outside of the gear ring 105. A motor 104 is installed at one end of the gear disk.

A hydraulic lifting column 106 and a support column 107 are installed on the top of the base plate 109. Rotary seats 108 are installed at both ends of the hydraulic lifting column 106 and the support column 107.

[0026] In this embodiment, the gear disk is electrically driven by the motor 104 to rotate. The gear disk meshes with the gear ring 105, thereby driving the ball mill 101 to grind the material. The hydraulic lifting column 106 extends and, in conjunction with the rotating seat 108, facilitates the lifting of one end of the ball mill 101, making it easier to load and unload materials. The vibration motor 205 generates vibration, which causes the bouncing balls 204 inside the screen 203 to vibrate, making the bouncing balls 204 continuously bounce and impact the screen 203, preventing material blockage on the screen 203. The vibration motor 205 facilitates faster material passage on the screen 203, thereby improving the screening speed and efficiency, shortening working time, and improving overall work efficiency. The collection box 202 facilitates the collection of screened material, the screen 203 facilitates material screening, and the buffer damper 206 provides a buffering effect.

[0027] The working principle of the embodiment is as follows: in use, first, the hydraulic lifting column 106 is extended, and the rotating seat 108 is matched to facilitate lifting one end of the ball mill 101, so that the ball mill 101 is conveniently fed; then the motor 104 is electrically driven to rotate the gear disc, the gear disc is connected with the gear ring 105 in meshing, and then the ball mill 101 is driven to grind the material; after grinding, the material is discharged into the screening box 201 through the discharge port 103; the collecting box 202 is conducive to collecting the screened material; the screen 203 facilitates screening of the material; at the same time, the vibration motor 205 works to generate vibration, drives the bouncing ball 204 inside the screen 203 to vibrate, so that the bouncing ball 204 continuously jumps in the screen 203 and impacts the screen 203, improving the screening speed and efficiency of the material; in the screening process, the air suction fan 304 works to generate suction, so that the dust cover 301 absorbs the dust generated during screening; the dust is collected in the dust collection box 303 through the communication pipe 302, effectively cleaning the dust generated during screening; finally, the movable sealing plate 308 slides in the sliding groove 307, facilitating cleaning of the dust collected in the dust collection box 303.
